Electrical Optical Characteristics at Ta=25
Parameters Symbol Min. Typ. Max. Unit Test Condition Viewing Angle [1] 2θ1/2 --- 120 -- Deg IF=350mA Forward Voltage [2] VF 1.6 --- 2.2 V IF=350mA Reverse Current IR --- --- 10 µA VR=5V Peak Emission Wavelength λp --- 730 --- nm IF=350mA Dominant Wavelength λd ---- 730 ---- nm IF =350mA Spectrum Radiation Bandwidth Δλ --- 10 --- nm IF=350mA Power Intensity Pv 160 --- 240 mw IF=350mA Notes:
- 2θ1/2 is the off axis angle from lamp centerline where the luminous intensity is 1/2 of the peak value.
- Forward Voltage measurement tolerance : ±0.1V
-
Notes:
1. Luminous Radiant is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
